FREDERICK A. WEGNER, 016 SILVER, CREEK, NEW YORK.

DUST-COLLECTOR.

To all whom it may concern:

Be it known that I, FREDERICK A. .VEG- nnn, a citizen of the United States, residing at Silver Creek, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Dust-Collectors, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to dust collectors of the cyclone type, in which dust or other solid matter is separated from air by reason of the rapid whirling of the dust laden air in a substantially conical separating chamber.

The invention has for its primary object to provide simple, inexpensive and efficient means whereby the tubular guard, or air discharge tube, may be suitably clamped in proper position upon the top or deck of the collector.

A further object of the invention is the provision of a tubular guard made in two main parts or sections, each of which is independently adjustable, and capable of being secured in fixed relation to the top of the collector when the collector is ready for use, it being understood that these adjustments are provided for the purpose of mm dering the action of the collector regulable my to most advantageously conform to its conditions of use.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter more fully set forth and claimed, it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings Figure 1 is a central vertical section of a dust collector embodying my invention;

Fig. 2 is transverse sectional view taken on the line 22 of Fig. I, and

Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 1.

Referring to the drawings, A denotes the separating chamber, which comprises the usual upper cylindrical portion 1, and a lower tapered or conical portion 2, terminating at its lower end in the usual dust discharge opening, not shown. The upper cylindrical portion is provided with the usual tangential inlet passage 3, for the Specification of Letters Patent.

dust laden air, and 4 represents the usual tubular guard or exhaust tube forming an outlet through which the purified air escapes. In the present instance, however, the tubular guard is arranged, for a part of its length, at an angle to the vertical," with its upper or outlet end portion concentric to the separating chamber or casing and with its lower or inlet end eccentrically disposed relative to theaxis of said chamber, such a structure being provided for a ,purpose as particularly described and claimed in my co-pending application, Serial No. 81,695, filed March 2, 1916.

The top or deck 5 of the collector is of theusual sheet metal construction, having an opening therein concentrically disposed relative to the axis of the collector, within which opening is supported the tubular guard, to which reference has heretofore been made. This tubular guard is constructed in two main parts, namely, an upper portion 6 extending without the casing or receptacle, and a lower portion 7, depending from the top of the collector and projecting within the separating chamber.

A tubular coupling member 8, preferably made of cast iron, is provided, and to this member is bolted, riveted, or otherwise secured, the lower portion of the tubular guard, the upperend of said lower portion being slipped in place over the lower end of the coupling member as clearly shown in the drawing, the securing means being passed through the overlapping portionsthereof. This coupling member is also provided with an outwardly extending circum ferential flange 9, the same acting as an element of the clamping means for securing the tubular guard in adjusted position upon the top of the collector.

The upper portion of the tubular guard, at its lower end, has an outwardly extending circumferential flange 10, which forms the other element of the clamping means, it being noted that. this end of the tubular guard is slipped over and surrounds the upper portion of the coupling member which projects upwardly through the concentric opening formed in the top and that by means to be more fully hereinafter referred to, the two sections of the tubular guard are drawn together and properly supported within said concentric open ing, the top of the collector beingclamped between the circumferential flanges 9 and 10.

of the collector,

An apron 1a is shown associated with the Within the frusto-conical member 15 of the guard and extending transversely across the same is a strut or bar 11, which is bolted or otherwise secured at its ends to the walls of said member, a similar strut or bar 12 being provided within the lower portion of the tubular guard, said strut extending transversely across the same and bolted at its ends to the walls of the tubular coupling member. Extending through perforations centrally arranged within these struts 11 and 12 is a clamping bolt 13 by means of which the two portions of the tubular guard may be drawn together in clamping position upon the top of the collector.

By the arrangement herein referred to, it will be noted that the tubular guard as an entirety may be securely arranged in fixed relation to the top of the collector, and is also capable of being knocked down and taken apart in the event it is necessary to make repairs to any of the parts. Furthermore, both sections of the guard, namely the upper and lower portions thereof, may be independently moved with respect to the top or deck of the collector, so as to bring about the proper positioning of these sections during assembly, it being further understood that the lower section of the guard may be adjusted or moved axially when desired so that thelower end of said section may be arranged in its proper eccentric position for obtaining efficient results. In this last mentioned regard it is to be noted that it is highly desirable to locate the lower end of the tubular guard wholly within the vortex of purified air within the collector, and as the axis of this vortex of purified air varies according to the conditions surrounding each particular installation, the herein described means of adjustment are provided for bringing about the desired results.

I claim 1. In a dust collector, the combination of a separating chamber, a sectional tubular guard supported within an opening in the top or deck of said collector, and means connected only to the tubular guard sections for effecting the clamping of such sections to the deck vof the collector.

2. In a dust collector, the combination of a separating chamber, a sectional tubular guard supported within an opening 1n the top or deck of said collector, a coupling member rigidly secured to one of said sections and cooperating with the other of said sections, and means carried by the sections for drawing the same together in connected relation and clamping them in proper position upon. the deck. a

3. In a dust collector, the combination of a separating chamber, a sectional tubular guard supported within an opening in the top or deck of said collector, a coupling member rigidly secured to the lower end of said sections, and having sliding engagement with the upper section, a clamping flange carried by said coupling member, a clamping flange carried by said upper section, and means for drawing the sections together in connected relation, whereby the top or deck of the collector is clamped between said clamping flanges and the tubular guard supported in proper position.

4. In a dust collector, the combination of a separating chamber, a sectional tubular guard supported within an opening in the top or deck of said collector, means for coupling together and supporting the sections in such coupled relation, upon said deck, a strut carried by each section, and a draw bolt engaging said struts and serving as a means for drawing the sections together in clamped relation to the deck.

. 5. In a dust collector, the combination of a separating chamber, a sectional tubular guard supported within an opening in the top or deck of said collector, a frusto-conical member supported within one of said sections, means for coupling together and supporting the sections in such coupled relation upon said deck, comprising a strut carried by said frusto-conical member, a similar strut carried by the other tubular guard section, and a draw bolt engaging said struts and serving as a means for drawing the sections together in clamped relation to the deck.

6. In a dust collector, the combination of a separating chamber, a deck for said collector having an opening therein, and a sectional tubular guard supported within said opening, the sections of which are held in clamped relation with respect to said deck.

7. In a dust collector, the combination of a separating chamber, a deck for said collector having an opening therein, a. sectional tubular guard supported within said opening, one section of said guard arranged without the separating chamber and resting upon the deck and the other section thereof located within the chamber and cooperating with the under side of said deck, and means for drawing said sections into clamped relation with respect to said deck.

8. In a dust collector, the combination of a separating chamber, a deck for said collector having an opening therein, a tubular guard associated with the deck of said collector, clamping plates carried by said tubular guard and cooperating with said deck on opposite sides thereof, and means for holding said plates in clamped relation with respect to said' deck.

9. In a dust collector, the combination of a separating chamber, a deck for said collector having an opening therein, a sectional tubular guard supported within said opening, a clamping plate rigidly secured to each section of said guard, one section of the guard and its clamping plate arranged without the separating chamber and resting upon the deck, and the other section and its clamping plate located within the chamber and cooperating with the under side of said deck, and means for drawing said plates in clamped relation with respect to said deck, thereby holding the tubular guard in position u on the deck.
